Case Reports Meta Analysis
Complete Corpus Callosotomy for Refractory Epilepsy in Children: a video article.
Corpus callosotomy is an interhemispheric disconnection by callosal commissural fiber ablation. Its rationale is the disruption of ictal spread to prevent seizure generalization. The objective pursued is alleviation of intractable, debilitating, and injurious manifestations of generalized epilepsy.1 Eight decades of experience support this procedure's safety and effectiveness for appropriately selected patients with drug-resistant epilepsy not amenable to optimal resection; particularly, favorable outcomes for tonic or atonic seizures with drop attacks have been reported.2,3 Children may benefit more than adults from callosotomy for improved daily function, psychosocial adjustment, and family satisfaction.4 A meta-analysis found a better seizure reduction from total than partial callosotomy (88.2% vs. 58.6% of worthwhile reduction) comprising drop-attacks (77.8% vs. 45.4%) with an increased but transient (i.e., resolution within 6 weeks) risk of significant disconnection syndromes (12.5% vs. none).5 Here, we present the illustrative case of a 4-year-old boy with Lennox-Gastaut syndrome who underwent open single-stage complete callosotomy. ⋯ We showcase critical steps such as dissection of cingulate gyri and anterior and then posterior callosotomy while highlighting crucial anatomic landmarks. This procedure may be accessible for epilepsy surgeons worldwide in resource-constrained environments6 while serving as a basis for promising high-technology development (e.g., endoscopic, radiosurgical, laser interstitial thermal therapy, or magnetic resonance-guided focused ultrasound callosotomies). In this video article, we aim to provide a streamlined and stepwise approach to this rare but important epilepsy surgery.

Review Case Reports
Supratentorial Neurenteric Cysts: Systematic Literature Review and Case Report.
Neurenteric cysts (NC) are uncommon congenital lesions with histopathologic properties derived from the gastrointestinal or respiratory tract. They are typically located in the intradural extramedullary compartment but rarely seen in the supratentorial region. The occurrence of supratentorial NCs (S-NC) presents an interesting quandary regarding their embryopathogenesis. ⋯ If surgically resected, the cyst wall specimen should be sent for pathology review, because of the potential risk for malignancy. If conservatively managed, serial imaging is warranted to track for changes that may indicate transformation. The embryopathogenesis of these rare congenital lesions remains incompletely understood, but the most comprehensive theory involves enteric cell migration to the neuroectoderm during embryogenesis.

Review
Endovascular Management of AVM-Associated Intracranial Aneurysms: A Systematic Literature Review.
Intracranial aneurysms are present in up to 18% of arteriovenous malformations (AVMs) and increase the risk of intracranial hemorrhage. No consensus exists on the optimal treatment strategy for AVM-associated aneurysms. The goal of this study was to systematically review endovascular treatment methods of AVM-associated intracranial aneurysms, radiographic outcomes, and periprocedural complications. ⋯ Endovascular management options of AVM-associated intracranial aneurysms are limited and mostly comprised primary aneurysmal coil embolization or parent vessel sacrifice using coils or liquid embolics. Embolization strategy depends on factors such as AVM angioarchitecture, rupture status, and adjunct AVM treatments.

Multicenter Study
Mindfulness training for young neurosurgeons: a virtual multi-centre prospective pilot study.
Burnout is prevalent among neurosurgeons and can negatively impact both technical and nontechnical skills and subsequent patient care. Mindfulness training has previously been shown to ameliorate the effects of burnout and improve performance in health care workers and high-stress occupations, but no such evaluation has been formally conducted for neurosurgeons. We aimed to determine the effectiveness and feasibility of a virtual mindfulness-based intervention (MBI) in neurosurgeons. ⋯ Preliminary evidence from this trial cautiously supports the effectiveness and feasibility of a virtual MBI for dealing with stress, burnout, and improving dexterity among young neurosurgeons. Further research is warranted to validate these findings.

Pedicular screws (PS) often are used in lumbar fusion. Cortical bone trajectory (CBT) is a novel technology in lumbar fusion with less evidence of clinical outcomes. Therefore, we conducted a meta-analysis to compare the efficacy and safety between CBT screw fixation and traditional PS in lumbar fusion surgery. ⋯ CBT reduced the rate of complications, surgical duration, blood loss, postoperative ODI, and JOA scores. The CBT technique, with better postoperative outcomes, achieved similar fusion rates compared with the PS technique.
